Abstract
A centrifugal pump separating gases from liquids pumps fluid containing gas comprises a pump housing divided into a working fluid chamber and an empty chamber by a baffle, the empty chamber connected to the working fluid chamber by an opening and connected to a gas separation assembly by a pumping chamber duct; an inlet for drawing liquid into pump, a outlet for pumping liquid outward and a separated gas exhaust port; an electric motor with protective cover drives an impeller cluster to create rotary movement; gas separator has a spring of sufficient hardness to control the gas discharge valve to open and close; this gas separator is connected to the empty chamber by the duct mentioned above and connected to the pump outlet by the bleed hole. During operation, when suction gas reaches a certain amount, reduced pressure at the pump outlet opens the valve to release the gas.
